<p>When is the meeting going to happen next week? If we stick to 1515 UTC, that would move it 1h earlier for me, which is okay. But if e.g. the compiler team meeting does NOT stick to UTC, but shift with DST (but then DST in which state/country? AFAIK not even all US states shift at the same time), that would make the two overlap.</p>
